Heres a cool way to earn from CLICK arbitrage.
-Become an Affiliate with several Comparison Shopping Engines (ie., Shopping dot com) etc...
A service like DatafeedScripts dot net even offers a turnkey solution.
-Be sure to select/promote products from a popular niche.
-Create a blog that targets your chosen product niche (ie., Photography blog => promote Digital Cameras as your product niche) .
Typically with Comparison Shopping Engines the higher value the product, the more you'll earn PER CLICK.
-One killer stealth tip to get immediate traffic to your blog is to promote a Giveway. In this example i'd give away a Digital Camera (you only need one

)
Only do this if you can afford to.
Then i'd list my GiveAway on networks. You can easily go on Fiverr and find several services that'll help you promote your GiveAway.
Note:: To run a GiveAway properly you'll need a tool like RaffleCopter, but there are TONS more. With a GiveAway you'll be able to get traffic
to your blog fast, gain more followers on Social Media, get clicks to your CSE affiliate store product links ($$$) & even build your mailing list (very important).
* For TRUE arbitrage... You can then either promote your blog OR your CSE (Comparison Shopping Engine) affiliate website using Bing,
FB ads, Pinterest ads, Youtube ads, Taboola etc...
Arbitrage is all about the SPREAD. If you can spend .20 cents on a click and earn .30 back, then you earn .10 cents. The objective is to
test and then scale your campaigns as fast as possible. The reason is campaigns get knocked off from time to time, which can ultimately
drive up ad costs as new competitors & copycats enter the picture.
This is why I mentioned creating a niche targetted blog.and alternate promo methods like GiveAways.
This way, you'll never have your eggs in ONE basket.
